CARBON-CARBON BOND FORMATION AND KETENIMINE SYNTHESIS FROM N-PHENYL IMIDOTHIOESTERS.

Methyl N-phenyl ethanimidothioate 1 and its α-silylated homologue 2 are metallated into lithiated enaminates which can be regioselectively monoalkylated at -78 deg C on the α-carbon atom.Imidothioester 2, treated at higher temperatures by 2 equivalents of BuLi, leads, after alkylation or hydrolysis, to stable silylated N-phenyl ketenimines.Formation of ketenimines are also observed by flash thermolysis of 2 or of the silylated S,N-ketene acetal 10.

Organic nitriles as insect antifeedants

Members of a novel class of organic nitriles related to an indole alkoaloid of Dithyrea wislizenii (Cruciferae) have been discovered to be potent feeding inhibitors of the fall armyworm and European corn borer.

Gas- Phase Ion Chemistry of Siloxide and Silamide Ions by Using the Flowing Afterglow. Unusual Rearrangements Involving SiO and SiS Bond Formation

Siloxide ions undergo O/S exchange reactions with suitable sulfur-containing neutrals, e.g.H3SiO- + CS2 -> H3SiS- + COS.Silamide ions similarly undergo NR/O and NR/S exchange reactions together with nucleophilic displacement reactions, e.g.: .No simple correlation between rate and mechanism is observed for all the studied reactions.
